Sen. Jim Justice is by far the wealthiest senator — at least on paper.

The West Virginia Republican disclosed owning over $1 billion worth of assets in 2024. The bulk of that value is tied up in various coal and mining companies that Justice owns, along with the luxury Greenbrier resort.

However, there's some reason to doubt that Justice is a billionaire.

Though he was listed as a billionaire by Forbes for several years, he was removed from the list in 2021 after it was revealed that he owed a significant amount of debt. Last year, Forbes reported that Justice and his companies were in so much debt, he had a negative net worth.

Spokespeople for Justice did not return a request for comment.

After serving as governor since 2017, Justice was elected to the Senate in 2024, succeeding retiring Sen. Joe Manchin.

Sen. Rick Scott is worth somewhere between $243 million and $744 million, according to his financial disclosure.

The Florida Republican's largest assets include his personal residence in Naples and a series of airplanes he owns, both of which are valued between $25 million and $50 million. The rest of mostly held in various investment funds.

Scott was elected to the Senate in 2018. He first entered politics in 2010, when he ran for governor of Florida and narrowly won the election.

Before that, he co-founded a chain of for-profit hospitals and was an investor.

Republican Sen. David McCormick of Pennsylvania owns assets worth at least $135 million, according to his 2024 disclosures.

That includes over $50 million in equity in Bridgewater, the hedge fund where he was CEO from 2020 to 2022.

McCormick also owns a ranch investment property in Colorado worth between $25 million and $50 million, plus other multimillion-dollar properties in Dallas, Washington, DC, and Pennsylvania. He and his wife also have significant investments in corporate, municipal, and US Treasury bonds.

The Pennsylvania Republican also disclosed liabilities worth between $14 million and $66 million, including a mortgage and a line of credit he took out in 2024.

McCormick was elected to the Senate in 2024 after defeating Democratic Sen. Bob Casey.

Sen. Tim Sheehy is worth at least $100 million — but he could be worth north of $300 million.

The Montana Republican's 2024 disclosure includes an ownership interest in an entity called "Turtle Lake Holding Company" worth over $50 million. The holding company holds millions of shares in Bridger Aerospace, the aerial firefighting company that Sheehy founded before entering politics.

He also disclosed owning two properties in Montana valued between $5 million and $25 million. His one liability, a mortgage, is valued between $1 million and $5 million.

Sheehy was elected in 2024, defeating Democratic Sen. Jon Tester.

Sen. Mark Warner is the wealthiest Democratic senator on Capitol Hill, boasting a net worth between $76 million and $303 million.

Much of the Virginia senator's wealth is tied up in various investment funds.

For example, he and his wife have between $7 million and $35 million in SPY, an exchange-traded fund that holds stock in all companies in the S&P 500 index. He also has millions invested in municipal bonds.

Warner was elected to the Senate in 2008. He was previously governor of Virginia, and before that, he was a venture capitalist who invested in a variety of tech companies.

Sen. Pete Ricketts is worth between $74 million and $293 million, according to his disclosure.

The Nebraska Republican is the son of Joe Ricketts, who founded the stockbroker TD Ameritrade and whose family owns the Chicago Cubs.

TD Ameritrade was acquired by Charles Schwab in 2020, and between $26 million and $155 million of the younger Ricketts's net worth comes from Charles Schwab stock.

He also has personal residences in Omaha and Washington, DC that are each worth between $1 million and $5 million.

Ricketts was appointed to the Senate in 2023, succeeding fellow Republican Sen. Ben Sasse. He was previously the governor of Nebraska.

Sen. Richard Blumenthal and his wife own at least $70 million in assets, making him the second-wealthiest Democrat in the Senate.

The Connecticut Democrat's disclosures indicate that the vast majority of that sum comes from various investments held by his wife, Cynthia, who is a member of the Malkin family.

Blumenthal's father-in-law, Peter Malkin, is the chairman emeritus of Empire State Realty Trust and Malkin Holdings. The family owns a stake in the Empire State Building.

Blumenthal was elected to the Senate in 2010, succeeding Sen. Chris Dodd.

Sen. Bernie Moreno owns at least $50 million in assets, according to his 2024 disclosure.

Much of that wealth comes from real estate holdings, including two residences in Florida, one in Washington, DC, and land in Ohio. He also has significant investments in mutual funds.

Prior to entering politics, Moreno owned a series of car dealerships and founded a blockchain company.

Moreno was elected to the Senate in 2024, defeating Democratic Sen. Sherrod Brown.
